Is God Unjust?
For [God] says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion." So then it does not depend on the man who wills or the man who runs, but on God who has mercy.
It’s a question of God’s fairness. If He only chooses some to be heirs of the promise and not others, people say that God is unfair. Yet Romans 9:16 teaches that people are not chosen or rejected because of who they were or what they had done or even would do. How can God elect one person and reject another before they were even born? God’s Word gives us the answers to these kind of questions.
